TW9992
Low Power NTSC/PAL Video Decoder with Differential CVBS Inputs and
MIPI-CSI2 Output Interface
DATA SHORT
To request the full datasheet, please visit www.intersil.com/products/tw9992
The TW9992 is a low power NTSC/PAL analog video decoder
that is designed for automotive applications. It supports
single-ended, differential and pseudo differential composite
video inputs. Integrated short-to-battery and short-to-ground
detection, advanced image enhancement capabilities such as
the programmable Automatic Contrast Adjustment (ACA) and
the MIPI-CSI2 output interface make the TW9992 an ideal
solution for demanding automotive camera applications.
